Joris Peels: 3D Printing Outside The Box

So I was thinking…what if you took an industrial robot, mounted an extruder on it and then put the resulting 3D printer on a chassis of some sort? A bomb disposal robot for example or a tank. You add some simple AI and sensors, such as the ones needed for soccer playing robots. Add the 3D printing/robot arm software and perhaps a remote control kill switch. ...

Peels proposes to abandon the "build chamber" concept entirely and use a robot arm mounted on a moveable chassis. 3D printing has previously been done with robot arms, but providing mobility would permit the arm to reach infinitely, enabling building massive objects.
